Hello,

Client also Debian Bookworm, Kernel 6.1.0-20-amd64, cifs-utils 2:7.0-2
The same with a second identical client.

After booting the Client journalctl shows on this client many lines like:

On the server I didn't found any errors.

please exuse my bad english, I want to report the following problem, maybe a bug: When mounting a samba-share by a Debian Bookworm client, kernel 6.1.0-20-amd64, on this client some subdirectories and files within the mounted share are missing. I didn't changed the permissions on the server and all the files and directories are furthermore existent on the server. Booting the client with kernel 6.1.0-15-amd64 oder 6.1.0-18-amd64 removes the error.
